Abstract and subjects

Arrays Diffraction Dynamic range Frequency modulation Metamaterials Resonant frequency
We design and test a switchable diffraction grating based on active metamaterials for terahertz modulation. We observe off-axis diffraction which permits operation of the device as a high-contrast modulator, with better than 20 dB of dynamic range.
